I am using log4j for logging,and using AoP interceptor for both Blogic and Filter Class ,Iam able to suppress the business runtime exception stacktrace for Blogic class,but same thing is not working with filter class
I have used aop pointcut for javax.servlet.Filter interface as shown below
Code:
<aop:pointcut id="filterBean" expression="execution(void javax.servlet.Filter.*(. .))"/>
<aop:advisor
pointcut-ref="filterBean"
advice-ref="blogicLoggingInterceptor"/>
blogicLoggingInterceptor bean is common for both Blogic and Filter Class
why the same code is not working for Filter Class 
Is it possible for filter class to prevent runtime exception stacktrace from getting registered into log file ?
any feedbacks are greatly appreciated
